From jsp through ajax cal I'm passing json string to server and I am converting to json object. How can I convert the jsonobject to a model class object in java?

In server I'm doing this:

 HttpServletRequest request = ServletActionContext.getRequest();
 String jsonData = request.getParameter("JsonData");
 JSONObject jsonDataObject = (JSONObject) JSONSerializer.toJSON( jsonData );

My model class looks like this:

   public class Vehicles {

private List<Vehicle> vehicle;

public List<Vehicle> getVehicle() {
    return vehicle;
}

public void setVehicle(List<Vehicle> vehicle) {
    this.vehicle= vehicle;
}
    
    }

And

  public class Vehicle{
    private Integer vId;
   private String VName;
   //getters and setters;
    }

How can I convert JSONObject jsonDataObject ( or String jsonData) to model class object(ie vehicles) in java?
